SVAN 958A Class 1 Four-channel Sound & Vibration
Analyser is dedicated for all applications that require
simultaneous class 1 sound and vibration assessment.
Each of four input channels can be independently
configured for sound or vibration detection with
different filters and RMS detector time constants giving
users an enormous measurement flexibility. The real
advantage of SVAN 958A is the capability to perform
advanced analysis simultaneously to the level meter
mode. In practise this allows the user to obtain broad-
band results such as Leq, RMS, LMax, LMin, LPeak
together with four-channel analysis like FFT or octave
band analysis.
SVAN 958A as sound meter meets IEC 61672-1:2013
and as vibration meter meets ISO 8041-1:2017. All
required weighting filters, transducers and adapters for
triaxial Whole-Body and triaxial Hand-Arm vibration
measurements (VM) are available with this instrument.
Additionally, in case of sound measurements (SM), each channel calculates simultaneously the results in three
independent profiles.
Advanced time-history logging, provides very powerful measurement capability. The external USB Memory
Stick extends this facility almost unlimitedly. Results can be easy downloaded to any PC using standard USB
(or optional RS 232 and IrDA) interface and SvanPC software.
Reverberation Time measurements, noise dosimeter and rotation speed measurements are available as
options for the SVAN 958A instrument.
The time-domain signal recording on the external USB memory stick is also available as an exceptional option.
Fast USB 1.1 interface (12 MHz) creates real time link for the PC "front-end" application of SVAN 958A. The
measurement results can be downloaded to PC using the above mentioned interfaces.
The instrument is powered by four AA standard alkaline or rechargeable batteries (i.e. NiMH – separate charger
is required). Powering the instrument from the external DC power source or the USB interface
is also possible. Robust and lightweight design accomplishes the exceptional features of this new generation
instrument.
The Whole-Body vibration measurement is now even easier thanks to the SV 38 seat-accelerometer which can
be placed directly on the seat-cushion, on the floor or fixed to the back of the seat.
The SV 50 set with triaxial accelerometer enables Hand-Arm vibration measurements regardless of the type of
evaluated tool.
Additionally, for measurements of very high impulse vibration the special adapter SA 55, with low pass
mechanical filter protecting accelerometer from DC shift effect is available. Evaluation of the grip force will be
possible with the dedicated “integrated adapter” SV 105 (under development).
